Reasons Why Hydraulics Equipment Should Be Charged Correctly

November 12th, 2018

Focusing once again on the mobile hydraulics sector, the moment has come to talk about equipment charging. Dynamically energizing the hydrostatic feed loop, a charge pump keeps the equipment responsive. After all, like it or not, hydraulic systems become less efficient as their circuits and circuit elements move away from the system’s prime charging unit. […]

There’s a simple mathematical progression that rules fluid technology. Applying the principle to hydraulic and pneumatic systems, it goes something like this: for every high-pressure, super-sized fluid system, a comparable rugged component must be sized and materially matched so that a quoted application functions properly. Enter composite construction cylinders, a technology that puts ultra-rigid cylinder […]

Hydraulic Pressure Intensifiers: How Can They Help Improve Your System Design?

October 16th, 2018

Hydraulic pressure intensifiers are built to deliver great quantities of pressure through a smaller than average package. Proven to take lower input energies and convert those fluid energies to higher output pressures, the device doesn’t need to break any laws of fluid thermodynamics when it performs this impressive feat. In reality, an intensifier (also known […]

Can Hydraulic Flange Misalignment Cause Leakage?

September 26th, 2018

Across two dimensions, a hydraulic flange misalignment error is causing trouble. The two collars are fastened evenly. All the way around, the bolts clamp the two faces together, with a seal or compound-jointed gasket adding integrity to the joint. Rotationally, however, the “twist” introduced by a rotational misalignment error is causing problems. Worse still, there’s […]

In-hand, a Fairey Arlon replacement filter feels hefty and solid. The component is cylindrical, filled with microglass, a media that functions well in hydraulic applications, and ready for duty. Slipping out of hand, it’s soon fitted as a hydraulic replacement filter, one that replaces the aging in-line fluid sieving device that’s clogging an essential piece […]

The Importance of Standard Testing for Hydraulic Hose and Fittings

August 27th, 2018

Hydraulic hoses add flexibility to what would otherwise be an entirely rigid system. That’s an ironic perk, considering the very flexible nature of the energy transmission fluid. But it’s true, metal tubing is rigid and fixed. In addition to flexibility, hoses isolate noise propagating vibrations. Loaded with benefits, then, flexible conduits and their fittings must […]

Filtration and Conditioning Hydraulic Systems: Do’s and Don’ts

August 17th, 2018

Tight dimensional tolerances exist between moving hydraulic components. There’s just not much clearance between the precision-manufactured parts as they slide past one another. Because of this tight-knit build, even a slight filtration problem is going to cause trouble. Equipment conditioning fails next, with heat reducing the system’s formerly efficient fluid workings. Avoiding these pitfalls, we’re […]

Chelsea Power Take-Off: Uses and Applications in Hydraulics

July 26th, 2018

A power take-off is a singularly focused piece of hydraulically powered equipment. The device receives energy from a power source, then that energy is transmitted to a separate fluid-powered device. Chelsea power take-offs push that fluid-mechanical principle to the limit. They’re built for heavy-duty applications, for big trucks and other workhorse usage domains. Look, there’s […]

Vane pumps work on a well-recognized principle. Mounted off-centre, a rotor spins in its pump housing. A number of bladed, or vanes, are fitted around this central section, and it’s those rotating elements that impart fluid energy. Applied to Denison vane pumps, the principle is the same, but the device architecture is more refined. Starting […]

Parker Axial Piston Fixed Pumps Uses and Applications

June 25th, 2018

Imagine a key hydraulic application. A generic fixed piston pump has decided to quit. The drive shaft stops spinning, the swash plate fails, and the cylinder block freezes. A company rep justifies the failure by talking about high operating pressures, but the excuses are far from satisfying. Parker axial piston fixed pumps won’t give out […]
